Single N-Channel, Logic Level, PowerTrench
®
MOSFET
GeneralDescription
This N-Channel Logic Level MOSFET is produced
using Fairchild Semiconductor's advanced PowerTrench
process that has been especially tailored to minimize
the on-state resistance and yet maintain superior
switching performance.
These devices are well suited for low voltage and battery
powered applications where low in-line power loss and
fast switching are required.
